Method Summary

void addAttribute(RuleAttribute attribute)


void addLhsItem(IPattern pat)


void addRhsItem(IAction action)


List getAllVariables()
          This will get a list of all bound variables, including bound fields.

FactPattern getBoundFact(String var)
          This will return the fact pattern that a variable is bound to.

List getBoundFacts()


List getBoundVariablesInScope(IConstraint con)
          This uses a deceptively simple algorithm to determine what bound variables are in scope for a given constraint (including connectives).

boolean isBoundFactUsed(String binding)


boolean isVariableNameUsed(String s)
          Checks to see if a variable is used or not, includes fields as well as facts.

Method Detail

getBoundFact

public FactPattern getBoundFact(String var)

This will return the fact pattern that a variable is bound to.

Parameters:: var - The bound fact variable (NOT bound field).
Returns:: null or the FactPattern found.

getBoundFacts

public List getBoundFacts()

Returns:: A list of bound facts (String). Or empty list if none are found.

removeLhsItem

public boolean removeLhsItem(int idx)

Parameters:: idx - Remove this index from the LHS.; Returns - false if it was NOT allowed to remove this item (ie it is used on the RHS).

isBoundFactUsed

public boolean isBoundFactUsed(String binding)

Parameters:: binding - The name of the LHS fact binding.
Returns:: Returns true if the specified binding is used on the RHS.

addLhsItem

public void addLhsItem(IPattern pat)

addRhsItem

public void addRhsItem(IAction action)

removeRhsItem

public void removeRhsItem(int idx)

addAttribute

public void addAttribute(RuleAttribute attribute)

removeAttribute

public void removeAttribute(int idx)

getBoundVariablesInScope

public List getBoundVariablesInScope(IConstraint con)

This uses a deceptively simple algorithm to determine what bound variables are in scope for a given constraint (including connectives). Does not take into account globals.

getAllVariables

public List getAllVariables()

This will get a list of all bound variables, including bound fields.

isVariableNameUsed

public boolean isVariableNameUsed(String s)

Checks to see if a variable is used or not, includes fields as well as facts.
